Spotlicht search on OS Xserver

I try to do a spotlight search on OSX server ( the client is connected to server ).
Is it possible in XOJO to search on the connected server drive instead of on the local hd.
In the language reference I cannot find any parameters to choose the drive to search on.

In the MBS plugins we have MDQueryMBS class.
There we have method

SetSearchScope(paths() as folderitem, options() as string)

so set where to search. This way you can limit search to one folder or volume.
